Xbox Live Gold 14 day trial - confusing and frustrating

"Everyone knows that" -> show me a link where it says that

This is only a trial subscription to play online, it's free and just a taste of Xbox Live Gold paid, Everyone knows that, there's no need of this advice

If you want to try the complete Live gold, use the link below to check if you're elegible for a 30 days of live gold (renew at the end of the 30 days, be carefull)

No problem, here's your link, enjoy ;-)

"If I redeem a promotional Xbox Live Gold token, will I be able to download the free games?

No, you would not be eligible. You must have a current Xbox Live Gold membership or trial that requires a credit card."

Dear Support,

Thank you for the fast reply!

Er...my question is that a 'xbox game pass ultimate 14 days trial codes' could be used/sold as 'xbox game pass 14 days trial code' or 'xbox gold live 14 days trial code', right?

I understand that a xbox game pass 14 days trial code or a xbox live gold 14 days trial code can't be used/sold as xbox game pass ultimate 14 days trial code for sure.

Because a 'xbox games pass ultimate 14 days trial code' equals a 'xbox game pass 14 days trial code + xbox live gold 14 days trial code', so for new Microsoft/Xbox accounts, a 'xbox game pass ultimate 14 days trial codes' could be used/sold as 'xbox game
pass 14 days trial code' or 'xbox gold live 14 days trial code' , right?

Please help to clarify.

Thanks again for your time!

straight from the back of the trial.At the end of your trial period, your 14 day xbox live gold trial will default to a FREE xbox live membership unless you elect to extrend your xbox live Gold membership. That infers that i should have actual Xbox live
Gold, not silver with multiplayer. so you can see why i'm a little confused
